Error Downloading Modpack!!!

[Mongoosem]

Since the latest launcher update, I can't use FTB. So ok, I figure a force update is in order. Nope,no go, it just get's an error. So I do a fresh install, and again, no go, still getting the error.
Is anyone else getting this error or better yet, found a fix?

Make sure your AV/firewalls didn't decide to start blocking it.
Creeper host could be having issues with the files, or there could be too many people trying to download it.
